Zinc in the epithermal environment

"The paper point out the zinc in the epithermal environmet. The zinc deposits are well known in a variety of sedimentary settings as well as in association with igneous centers, but have attracted little attention in theepithermal environment. Nevertheless, zinc accompanied by gold and silver occurs in several styles of both high- and intermediate-sulfidation epithermal mineralization. However, low-sulfidation deposits are everywhere zinc-poor. High-grade epithermal zinc deposits are hosted by carbonate rocks in transition zones between the HS and IS environments, whereas large tonnages of lowgrade epithermal zinc mineralization of either HS or IS type occur in diatreme breccias or impregnate lacustrine sedimentary rocks around volcanic centers."
